I'm having this problem that's making me lose my mind. I have not been able to find any solutions here on tomshardware or any other forums so I've decided to make my own thread.
Ever since I built this PC, I have been having this bizarre problem with videos slowly losing sync with audio. The problem occurs on Twitch and Youtube in both Chrome and Firefox and also happens with downloaded videos in VLC player. It seems like it just applies to any video player. The audio is absolutely fine, but the video plays in the slightest, almost unnoticeable slow motion and gradually loses sync with the audio more and more. Usually restarting the browser or the player refreshes it and it starts slowly losing sync again.
The problem most often occurs while I'm playing a game (not to the game, but to the other applications running on the other monitors). Very rarely has it started without me playing a game or streaming with OBS first.
Now, here comes the part that confuses me so much. This new PC I built includes the same EVGA GeForce GTX 1080 SC GPU I was using in my old PC, which didn't have this problem. But by switching my 1080 for a 970 in my new PC, the problems stopped. Putting my 1080 in another almost identical PC to my new one caused the same problem to occur in that PC. So naturally, I thought there was suddenly a problem with my 1080. I submitted my 1080 for a cross-shipment RMA, and the replacement 1080 I received produced the EXACT same problem. So is this a problem with this specific 1080 model and some other piece of hardware in my PC/the other PC that had the same problem? Both my new PC and that PC have the same CPU and very similar motherboards.
I have tried so many GPU driver versions, including the driver I last used in my old PC. And it seems like the problem goes away for a day or two after I perform a clean install of my GPU driver.
Things I have tried to fix the problem using my 1080:
Turning off hardware acceleration in Chrome
Updating all drivers
Flashing BIOS
Running all monitors at 60hz
Formatting Windows
Uninstalling Realtek Audio drivers
Setting all power settings to performance-based
Overclocking CPU
Rigs that have the problem occur with my 1080:
#1
CPU: Intel i7 8700k (stock)
Mobo: ASUS ROG STRIX z370-F
RAM: Corsair Vengeance 16GB DDR4 3200mhz
PSU: Seasonic Focus Plus 650W Gold
#2
CPU: Intel i7 8700k @4.9ghz
Mobo: ASUS ROG STRIX z370-G
RAM: Corsair Vengeance 16GB DDR4 2400mhz
PSU: Corsair CX600 600W
Rig that did NOT have the problem occur with my 1080:
CPU: Intel i7 4790k @4.5ghz
Mobo: Gigabyte GA-z87X-D3H
RAM: Corsair XMS3 DDR3 1600MHz
PSU: Corsair CX600M 600W
All PCs are running Windows 10.
If anyone here has any suggestions or experience with this problem, I'd be so grateful. This problem is really driving me crazy.
